How to clear caching in Drupal 7

Setting up cache in Drupal can speed things up for your site and enhance the site's overall performance. Caching is great as it keeps snapshots of data and pages so reload time is much quicker. There are times, however, when you may need to clear the cache. Caching mechanisms sometimes get hung or maybe you simply want to push out a change to your site as quickly as possible. Clearing the cache can help with that. It is very easy to clear caching within Drupal 7 by folloing these simple steps.

When you have caching enabled in Drupal, this is the intended result, with old content being cached until the cache is cleared out. You might also see if you can clear out your local web-browser's cache to see if you can see your new nodes after adding them that way.

On the Performance screen mentioned in this article, you could reduce the time for the Expiration of cached pages, so that it doesn't cache them for very long. However leaving this setting at a low interval can have a negative performance impact due to the cache not being used as it's constantly reset.
